Description

Technical Field

[0001] This invention relates to the field of bimetal band saw blade technology, specifically a tensioning device for a bimetal band saw blade quenching and tempering production line. Background Technology

[0002] Bimetallic saw blades are made by vacuum welding two types of steel with different characteristics using an electron beam, followed by a series of processes including annealing, precision rolling, leveling and straightening, milling, tooth splitting, and quenching and tempering.

[0003] During the quenching and tempering process of bimetallic band saw blades, material changes during tempering can cause deformation of the saw blade, leading to slackness during transport and a risk of accidental ejection, resulting in poor safety. Furthermore, due to variations in the saw blade material, two or more tempering cycles may occur. During these repeated tempering processes, the slack state of the saw blade makes it difficult to control its orientation within the furnace, potentially causing deviations in the tempering effect and impacting product performance.

The other end of the rotating shaft 9 passes through the housing 1 and is axially connected to the inner wall of the housing 1. Gears 10 are welded to the outer wall of the rotating shaft 9. The rotating shaft 9 drives the gears 10 to rotate clockwise. There are two gears 10, located on the front and rear sides of the outer wall of the rotating shaft 9. Gear 10 is a half gear.

[0034] As a preferred embodiment, the transmission wheel 20, the first guide wheel 21, and the second guide wheel 22 are all the same size and shape.

[0035] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0036] In use, first connect the device to an external power source. First, rotate the first reduction motor 30 clockwise. The clockwise rotation of the first reduction motor 30 drives the swing arm to rotate clockwise at a constant speed. The swing arm drives the annular slide rail 31 to slide left and right. The annular slide rail 31 drives the push block 26 to slide left and right. The push block 26 drives the first guide wheel 21 to rotate clockwise via the inclined rod 18. The first guide wheel 21 drives the second guide wheel 22 and the transmission wheel 20 to rotate clockwise simultaneously via the crossbar 19. This achieves simultaneous rotation of the transmission wheel 20, the first guide wheel 21, and the second guide wheel 22 in the same direction and at the same speed, thus transmitting power to the bimetal band saw blade 2. When tensioning of the bimetal band saw blade 2 is required... When the second geared motor 8 is connected to an external power source, the second geared motor 8 rotates clockwise, causing the reducer to rotate clockwise, which in turn causes the rotating shaft 9 to rotate clockwise. The rotating shaft 9 drives the gear 10 to rotate clockwise, and the gear 10 drives the guide rail 12 to move upward. The guide rail 12 drives the second vertical rod 14 to move upward, and the second vertical rod 14 drives the horizontal plate 15 to move upward. The horizontal plate 15 drives the vertical plate 17 to move upward, and the vertical plate 17 drives the horizontal shaft 16 to move upward. The horizontal shaft 16 drives the third rotating wheel 3 to move upward, and the upward movement of the third rotating wheel 3 tightens the bimetal band saw blade 2. This design has a simple and reasonable structure, strong applicability, and is beneficial for widespread use.
